In Switzerland January 9, 1950 Claims.

'I'he present invention relates to a sprinkling bottle or spray and inparticularto a spray of which al1` the parts are easily accessible andwhich accordingly can be cleaned rapidly and well.

A sprinkling bottle or spray according to this invention has mounted inan air bulb a liquid container to which is attached a sleeve membercarrying a dip tube, the said liquid container having an attached airtube which passes through it and into the sleeve member from the airbulb to a point adjacent to the exposed end of the dip tube and thesleeve member having an opening for the sprayed liquid suitably locatedwith respect tothe air and dip tubes.

In its preferred form the spray has a cap on the sleeve member forcovering the opening for the sprayed liquid when the spray is not inuse.

The sleeve member is suitably provided at the base with a ilangedportion and a plug portion for fitting the mouth of the liquidcontainer.

The plug portion and the mouth of the liquid container may be providedwith a key and keyway for positioning the sleeve member with respect tothe liquid container.

The neck ofvthe'liquid container may be provided with a screwed-on ringhaving an inturned portion engaging a ilange at the base of the sleevememberto attach the sleeve member to the liquid container.

An annular channel may be provided between the nturned portion'of thering and the wall of the sleeve member, a drain opening may be providedin the said wall within the said channel and a drain hole may beprovided at the base of the sleeve member draining into the liquidcontainer.

'Ihe cap may have two spaced internal screw threads for engaging anexternal screw thread on the sleeve member, the cap moving freelybetween the two engaged positions, in one of which the opening for thesprayed liquid is covered and in the other of which it is exposed.

The invention is illustrated in the accompanying drawing.

Figure 1 of the drawing shows a sprinkling bottle or spray according tothe invention in longitudinal section, partly in elevation,

Figure 2V shows a longitudinal section at right angles to the section ofFigure l and Figure 3 a section on the line A`B of Figure 1.

In the drawing an air bulb is indicated by I and a liquid container by2. As shown in the drawing the mouth 3 of the bulb engages, in a manneralready proposed, in an annular groove 2 4 of the liquid container 2.Through the base 5 of the container 2 there passes in known manner anair tube Ii which penetrates into a sleeve member 1 located on thecontainer 2, extending to a height corresponding to an opening 8provided in the wall of the sleeve member TI. The sleeve member has abase 9 which is provided with a flange 9a. The flange 9a has a plugportion I9 which ts into the mouth of the liquid container 2. A dip tubeII passes through the base 9 of the sleeve member I almost to the bottom5 of the liquid container 2. The dip tube II is rigidly attached to thebase 9 so that it is carried thereby. In the base 9 is provided anopening I2 through which passes the air tube 6.

The exposed end I3 of the dip tube II is located immediately under anupper opening III of the air tube 6. In order to ensure that in ttingthe sleeve member 'I on the liquid container 6 the opening I4 is alwaysopposite'the opening 8 of the sleeve member I so that the atomisedliquid can pass unhindered out of the spray, a key I5 is provided at apoint on the plug portion I0 and a keyway I6 on the mouth of the liquidcontainer 2 corresponding to this key. By virtue of this arrangement ofa key and keyway the sleeve member with its opening 8 and the liquidcontainer 2 with the air tube 6 which cannot be displaced with respectthereto, are always in the same position relatively to one another.

In order to prevent displacement of the sleeve member "I from the liquidcontainer 2, a screw thread is provided on the neck I'I of the liquidcontainer 2 to receive a ring IB, the inturned edge I9 of which becomesrigidly positioned on the flange 9a of the base 9 of the sleeve member'I.

Between the inturned edge I9 of the ring I8 and the Wall of the sleevemember 'I there is an annular channel 20. Within this annular channelthe wall of the sleeve member I has an opening 2|. Since an opening 22is likewise provided in the base 9 any liquid droplets which are formedin the spraying of liquid can drain down the wall of the sleeve member Iinto the annular channel 20 and from there through the openings 2| and22 back into the liquid container.

As is seen from the drawings the sprayl has a cap 24 which serves forcovering the opening 8 of the sleeve member I. In order that the capshall not interfere with the manipulation of the spray and in orderfurther to prevent the cap from being mislaid when the spray is in use,screw threads are provided onthe inner surface of the cap at each of theupper and lower rims, which are indicated in the drawing by 25 and 26.

The sleeve member 1 has at its upper rim a screw thread 21 correspondingto the screw threads 25 and 26. As shown in Figure 1 the cap 24 isscrewed with its lower thread 26 on the thread 21 ofthe sleeve member 1;in this case the opening 8 is exposed. According to Figure 2 the cap 24is located with its upper thread on the thread 21 of the sleeve member 1so that the spray is closed. In order to achieve a good air-tightclosure the lower rim 28 of the cap 24 and the upper rim 29 of theinturned portion I9 of the ring I8 are correspondingly inclined withrespect to one another so that the cap 24 fits with its rim 28 closelycontacting the rim 29 of the inturned portion I9.

An advantage of the sprinkling bottle or spray according tothe inventionlies in the fact that with little handling it can be dismantled so thateach part becomes easily accessible and can be cleaned. This is ofparticular importance as regards the dip tube Il which may becomeblocked up. In order to be able to clean the dip tube, rst the cap 24 iscompletely unscrewed from thev sleeve member, then the ring I8 isunscrewed and the sleeve member 1 together with the dip tube. Il canthen be withdrawn from the liquid container 2. The dip tube may beprobed by means of a thin wire from the lower end towards the top; sucha wire can be fitted into the bottom of the liquid container 2.

In order to carry the invention into eiect no special materials arenecessary. For the liquid container and the sleeve member a transparentplastic is suitable for example.
